Relaymove tweaks (#19489)

Made relaymoves uniform in function header and non sleepable.
Improved IPC/borg recharger, made it time constant.
Tweaked client/Move() to avoid a range(), moved a relaymove around to
fix a bug, some minor tweaks.
Fixed IPC/borg recharge station not taking the IPC/Borg in on bump.
